Habitats and landscapes
The Natural Heritage Inventory has developed scores indicating the degree to which each of Wisconsin's rare plant species is associated with a particular natural community or ecological landscape. This information is similar to that found in the Wildlife Action Plan for animals. As this is a work in progress, we welcome your suggestions and feedback.
General habitat information
- Habitat description: Found on sand dunes and old beach ridges near Lake Michigan.
- Soils: Sandy soils.
Natural communities
This table lists the natural communities that are associated with Sand Coreopsis. Scores for natural community associations are: "significant" association (score=3), "moderate association" (score=2) or the species can be present but is only weakly associated with the community (score=1).
| Natural communities | score |
|---|---|
| Great Lakes Ridge and Swale | 2 |
| Great Lakes Dune | 3 |
Ecological landscapes
This table lists the ecological landscape association scores for Sand Coreopsis. The scores (3=High, 2=Moderate, 1=Low, 0=None) also correspond to the map.
| Ecological landscape | score |
|---|---|
| Central Lake Michigan Coastal | 3 |
| Central Sand Hills | 1 |
| Northern Lake Michigan Coastal | 3 |
Species guidance
The Endangered Resources Program has developed avoidance measures and management guidelines for plants on the Natural Heritage Working List. These are a work in progress, and we welcome your suggestions and feedback. Sources used in developing this information can be found here.
Avoidance measures
These are specific actions designed to avoid "take" (mortality) of this species.
- No avoidance measures have been developed for this species.
Management guidance
Management guidelines are additional considerations that may help maintain or enhance habitat for this species
- Avoid any activities which destabilize the dune, including the use of off-road vehicles, removal of native vegetation and pedestrian recreational overuse.
- Minimize disturbance to hydrology, including soil disturbance from rutting.
- Avoid disturbance to shorelines and the forest-beach interface.
